PORTSMOUTH — Police are investigating the report of an attempted robbery Tuesday night, when someone reported being struck with a “blunt object” by a masked man who demanded money.

Officers were dispatched to the area of Sheridan Avenue at about 8 p.m. Tuesday, when the victim said he was assaulted while getting into a car. The alleged assailant is described as a white male, about 6 feet 2 inches tall and with light-colored, short hair. He was wearing a hooded sweatshirt with writing on it and his face was covered during the attack, police said.

After the assault, the suspect ran to a waiting car, got into the front passenger side and left the scene, according to police. The getaway car is described as a dark-colored four-door sedan with a 7-digit license plate, possibly a “boxy” style sedan, police said.

The victim suffered injuries described as minor and refused medical attention at the scene, police said.

Anyone with any information is urged to call officer Matthew Young at 610-7619.
